Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2022-28614)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the ap_rwrite() function. A remote attacker can with the ability to force the server to reflect a very large input using ap_rwrite() or ap_rputs() (such as with mod_luas r:puts() function) can trigger an out-of-bounds read error and read read unintended memory on the system.
2) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2021-40438)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input within the mod_proxy module in Apache HTTP Server. A remote attacker can send a specially crafted HTTP request with a chosen uri-path and trick the web server to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
3) Improper Authentication (CVE-ID: CVE-2022-31813)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in mod_proxy implementation, where the web server may not send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. A remote attacker can bypass IP based authentication on the origin server/application and gain access to otherwise restricted functionality.
4) Out-of-bounds read (CVE-ID: CVE-2022-30556)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when processing HTTP requests in mod_lua with websockets. A remote attacker can force the module to return lengths to applications calling r:wsread() that point past the end of the storage allocated for the buffer and gain access to sensitive information.
5) Resource exhaustion (CVE-ID: CVE-2022-30522)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to mod_sed does not properly control consumption of internal resources, if the web server is configured to do transformations with mod_sed in contexts where the input to mod_sed may be very large. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
6) Input validation error (CVE-ID: CVE-2022-29404)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when processing HTTP requests to a lua script that calls r:parsebody(0). A remote attacker can send a very large HTTP request to the affected web server and perform a denial of service (DoS) attack.
7) Out-of-bounds read (CVE-ID: CVE-2022-28615)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the ap_strcmp_match() function when processing an extremely large input buffer. A remote attacker can send a specially crafted HTTP request to the web server, trigger an out-of-bounds read error and read contents of memory on the system.
Note, the code distributed with the Apache HTTP Server cannot be coerced into such a call. The vulnerability can affect third-party modules or lua scripts that use ap_strcmp_match().
8) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-26377)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests in mod_proxy_ajp. A remote attacker can send a specially crafted HTTP request to the server and smuggle requests to the AJP server it forwards requests to.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
9) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-33193)
The vulnerability allows a remote attacker to preform HTTP/2 request smuggling attacks.
The vulnerability exists due to improper validation of HTTP/2 requests in mod_proxy in Apache HTTP Server. A remote attacker can send a specially crafted HTTP/2 request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison web server cache and perform phishing attacks.
10) Out-of-bounds write (CVE-ID: CVE-2022-23943)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in mod_sed. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.
11) Integer overflow (CVE-ID: CVE-2022-22721)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the ap_escape_html2() function when parsing LimitXMLRequestBody. A remote attacker can send a specially crafted request to the web server, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
12) Input validation error (CVE-ID: CVE-2022-22719)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to use of uninitialized value in r:parsebody. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
13) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2021-44224)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in forward proxy configurations. A remote attacker can send a specially crafted HTTP request and trick the web server to initiate requests to arbitrary systems or cause NULL pointer dereference error and crash the web server.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
SSRF if possible for configuration that mix forward and reverse proxy.
14) Buffer overflow (CVE-ID: CVE-2021-39275)
The vulnerability allows a remote attacker to execute arbitrary code on the target system or perform a denial of service attack.
The vulnerability exists due to a boundary error within the ap_escape_quotes() function. A remote attacker can send a specially crafted request to the web server, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that the Apache module passes untrusted data to the affected function.
According to vendor, No included modules pass untrusted data to these functions
15) Out-of-bounds read (CVE-ID: CVE-2021-36160)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition in the mod_proxy_uwsgi module in Apache HTTP Server. A remote attacker can send an HTTP request with specially crafted uri-path, trigger an out-of-bounds read and perform a denial of service (DoS) attack.
16) NULL pointer dereference (CVE-ID: CVE-2021-34798)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can send a specially crafted HTTP request to the affected web server and perform a denial of service (DoS) attack.
